T0 all wwm, it may concern,.-

Be it known that I, JEAN SCHNEEWEIS, en-

gineer, a subject of the Emperor of Germany,

tors, of which the following is a specification.,

My present invention relates to a, novel motor in which the transmission of power from the piston to a fly-wheel or a drivingsheave does not take place through the medium of a connecting-rod crank or crankshaft,but through a rod fixed to the piston and guided by the fly-wheel. The object of this arrangement is to avoid the following objectionable results from a crank-machine: first, the rapid loosening of the piston in consequence of the irregular wearing of the cylinder and piston-wall; second, the rapid Wearing out of the link and bed; third, the racking of the building, vehicle, or ship by gasmotors in consequence of the explosive stroke in the cylinder, and, fourth, the vibration of the machine and the foundation bythe swinging structure.

In the accompanying drawings the motor is illustrated as a gas-motor, the several elements for mixing the charge and the controlling and igniting apparatus, however, being omitted for clearness.

The novel features of my invention maybe applied to a steam-engine, a hot-air engine, or other forms of motor with equal advantage.

In said drawings, Figure l is a vertical section taken through the motor on the line A B of Fig. 2. Fig. 2 is a horizontal section on the line O D of Fig. 1. Fig. 3 is a vertical section on the line E F, Figs. l and 2. Fig. 4 shows the driven member of the engine in different relative positions to the driving connection.

a is a piston, which to avoid vibration of the building, vehicle, or ship to which the engine may be applied, as well as to avoid destructive vibration in the machine itself, has

its vibrating parts duplicated and symmetrically arranged. Rigidly connected to the piston are driving connections consisting of the stems Z), the cross-arms c, the bars d, sliding in the guides c, and rollersf, mounted upon the bars CZ and providing projections for engaging and operating the driven membersof the motor. There are four pairs of projecting studs provided by the rollers f, one pair being mounted upon each of the bars d, and these pairs of studs engage on the inner and outer faces of two symmetricallyformed cam-like slide-rails g, arranged upon the respective fly-wheels 7L. These wheels are mounted upon spindles t' and provided with belt-sheaves k or with toothed wheels or other suitable means for transmitting rotary movement from the fly-wheels. The form of the slide-rails g will be determined by the stroke of the pistons and the number of strokes which the latter make for eachrevolution of the fly-wheel. In the motor shown in the drawings the pistons make two strokes foreach revolution of the iiy-wheel, and consequently the form of the slide-rails g is elliptical, or other forms will necessarily be adopted if it is desired to increase the number of strokes of the pistons for each revolution of the ily-wheel, the selection of the form being obviously a mere problem in construction. The inner and outer faces of the rails g are necessarily formed upon dissimilar ellipses, because the line drawn through the axes of the rollers f is not always normal to the ellipse. Hence the thickness of the sliderails must vary according to the position of the rollers. This will be understood from the vdiagram shown in Fig. 4. .In order to prevent heating the guides e for the bars d, said guides are not mounted directlyupon the cylinder jacket, but are secured thereto through the medium of the air-cooling ribs m or water-cooling channels a.

As previously stated, theinvention is shown for purposes of illustration as applied to a gas-motor and suspended from the bottom 0 of an automobile vehicle through the medium ofthe hangerp.

gas and air valve and other parts would be mounted upon the projection q.

If the invention werel applied to a steamengine, the controlling mechanism would like- The actuatwise be located at this point.

In such an arrangement the IOO ing of the valve or slides for controlling the admission of fuel or of steam to the cylinder would be operated in any well-known manner-such, for instance, as by a connection with the fly-Wheel.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:

1. A motor for steam, gas, hot air, or the like, comprising a rotary driven member, a cylinder, a piston located in said cylinder, and means for imparting the reciprocating motion of the piston as a rotary movement to the driven member, consisting of a bar reciprocated in a straight line by the piston and provided with projecting studs, and an endless elliptical slide-rail carried by, and in a plane parallel to, the driven member, and engaged by the studs; substantially as herein set forth.

E3. A motor for steam, gas, hot air and the like, comprising a cylinder, a reciprocating piston moved by power introduced into said cylinder, a fly-Wheel provided with a calnlike slide-rail, a stem connected to the piston, slide-bars moved bysaid stem, and studs projecting from the slide-bars, and engaging the cam-like slide-rail on the fly-wheel substantially as herein set forth.

43. In a motor for steam, gas, hot air and L the like, the combination ot' oppositely-reuiprocatin g pistons, fly-Wheels carrying cam-like slide-rails, and reciprocating bars connected with the respective pistons and provided with projecting studs engaging on opposite sides of the respective cam-like slide-rails; substantially as herein set forth.

4. In a motor, the combination of a cylinder, a piston reciprocating in said cylinder, a slide-bar reciprocated in a constant line by said piston, projections on said slide-bar, and a fly-Wheel provided with an endless elliptical slide-rail in a plane parallel thereto, with which projections on the slide-bar engage at diametrically-opposite sides; substantially as herein set forth.

The foregoing specification signed at Frankforton-the-l\Iain, Germany, this 7th day of December, 13.00.
